multiple calls to cURL

I have a page on which a cURL is performed and takes a few seconds to complete.
I was wondering what would happen at the server if few users accessed that page at the same time.
My guess is that each user will be given his/hers own time (say 5 seconds), but it should not affect each others waiting time, or should it ?

Thanks

Impossible to say because there are too many unknown factors¹, most notably the number of users hitting you within any one 5 sec interval. But for a sanely small number of users it should be fine.

¹ For example: how many requests can/will your setup serve concurrently? what about the remote curl target?

It all depends on resources.

If the processing of your requests takes five seconds because of heavy file I/O, simultaneous requests might slow down the other ones, doubling the time required for each requests.

Same goes for bandwidth: is it a lot of data you're requesting? Then multiple simultaneous requests might impact each other, given a maximum bandwidth the upstream server can assign to a single connection and its total bandwidth.

Furthermore, when the processing of the (result of the) request takes up a (relative) lot of processor time, firing multiple request at one can slow down each request.

Yes of course. Because it's multithreaded. Requests don't interfer between each other (if they are not too many)
